The OCA test

First, select the "cheat mode" you'd like to use. Selecting "No cheating" (default) gives you a blank sheet if you'd like to do the test without cheating. On the other hand, if you'd like to experiment a little, or is lazy, you can select one of the following options: "Low/high scores" gives you a sheet with defaults that will give you the lowest/highest score possible, while "Random" gives you a randomly filled in test.
